Global Thermometer from 20,000 BCE to Now

You know this global warming thing? Ever wondered how the Earth’s temperature has changed over the millennia? Well here’s your answer….. planetary temperature for the last 20,000 years. Yeah, that’s well longer than when Creationists say that God created everyone so if you believe that nonsense, you won’t want to bother with this. If you’re for having a look, then make sure you don’t stop until the very end. That’s where it gets frightening. Oh and Creationists? You do know that you’ll have to come up with anther explanation for what happens after 1950?
